iPod Touch 1g wall charger?

Hey guys,
I got 2 of these (1 and then a replacement) http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=220452832939&ssPageName=STRK:MEWNX:IT
However, none of them worked on my 1g!
I have proper plugs usb cables etc. and the chargers work on my nano!
I read online that some wall chargers don't work on iphone/ipod touches.So can someone give me an ebay link so a wall charger you used that worked for ipod touch? thanks! and please have it under $4 or $5 .
Thank you!

Hi...
Well I guess that a Wall USB charger works well with 1G IPod I personally have 1G nano and i can easily charge it with Wall charger.Though i would tell you to buy Apple's charger too.Its really nice to use it.Well select the appropriate one which satisfies your requirement.Stay connected.
